Version 0B released. This is a minor update, corrections below (or see release notes in the zip file).

The buffer created by Ladybug is no longer removed by "PACK" or "GTO ..". The buffer would previously be removed if such operation was invoked before turning the calculator off (at least once).

Ladybug now works properly with very early HP-41C calculators.

No longer crashes if another module misbehaves and leave a secondary bank enabled when returning to the operating system, and that module is located in such a way that the bank switch mechanism is shared with Ladybug.

Minor change to the module file metadata to avoid any possible confusion to the module reader on how to group and locate the pages.

(This time it also includes the .pdf version of the documentation.)

Original post:

I am happy to finally have an HP-41 module to announce!

It is called Ladybug and offers an integer mode, similar to what is provided by the HP-16C. This release is for early adopters and is labelled version 0A.
